Equivalent Circuit Model Parameters Extraction for Lithium Ion Batteries Using Electrochemical Impedance Spectroscopy

Popis výsledku v původním jazyce

Numerical modelling is the method by virtually testing and verifying the functionality of a specific product or component. The primary goal is to get approximate results of how the system behaves in a given time and environment. We are able to accept a certain numerical error from a real experiment, thus significantly speeding up part of the development of the device. In the field of electrochemistry of lithium-ion accumulators, several variants of numerical models have been proposed that yield satisfactory results in modelling certain physical fields of these batteries (electric field, temperature field, current field). One model is the battery model with its equivalent circuit, which is represented by passive components, namely a resistor and a capacitor. This is a model that describes the internal behaviour of a battery by RC circuit. However, the problem is to find or measure these parameters. One way to get the parameters of this spare circuit is by means of electrochemical impedance spectroscopy (EIS). This article deals with the application this method to obtain the parameters of the equivalent battery circuit and comparing the charging and discharging curves of a specific battery with the ECM model.
